"Luddington lock is now the site of the old footbridge over Bancroft Basin Lock which was built by prisoners in 1963 at their workshops in Wormwood Scrubs, London, placed in position by the Royal Engineers, Long Marston in 1964 and installed by prisoners from Winson Green in Birmingham. Volunteers took the opportunity to bring this iconic structure back to its former glory."
The bridge is on the site of the original round Upper Luddington lock.

The caravans are still at Bredon Marina, the other side of Bredon Dock. There have only been moorings at the Old Rectory.
The Old Rectory is about 30' higher than the river. If that ever floods, then most of Tewkesbury would be under 30' of water!

The danger of the rudder being wedged in between the gates when ascending locks was recognised in the 'Standards for the equipping and construction of pleasure boats and houseboats using the Board's waterways', which were published in May 1981.
Section A13 stated that boats fitted with a rudder which extends longitudinally aft of the hull should be 'fitted with a stern fender secured to prevent the rudder being trapped between the mitres of lock gates,'
